COW-YOKE.

Specification of Letters Patent.

Patented Aue. i9, 1913.

Application tiled October 9, 1912. Serial No. 724,893.

To all whom t may concern:

Be it known that I, ABBOTT S. PARKER, a citizen of the United States, re 'iding at Abernathy, in the county of Hale and State of Texas, have invented certain new and useful Improvements in Cow-Yokes, of which the following is a specification, reference being had to the accompanying drawings.

rIhis invention relates to new and useful improvements in animal pokes and more particularly to a cow-yoke and the primary object of the invention is to'provide a device of this character which will positively prevent the animal from poking his head through a wire fence.

A further object of the invention resides in providing a yoke formed in sections pivoted one to the other and to which are connected spurs which are adapted to be disposed toward the plane of` the projection of the longitudinal center of the yoke as the sections of said yoke are swung on their pivots.

Still another object of the invention resides in providing a device which is eX- tremely simple and durable in construction, inexpensive to manufacture and one which will be very efficient and useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing forming a part of this application, Figure l is a perspective view showing my device applied to the neck of an animal. Fig. 2 is a side elevation of the device in bent or effect-ive position and showing in dotted lines the normal and ineffective position of the same. Fig. 3 is a transverse section therethrough as seen on line 3-3, Fig. 2; and Fig. 4 is a horizontal section through the device as seen on line 1 -4, Fig. Q. i

In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which l indicates a yoke composed of pairs of arcuate arms 2 and 3, said pairs of arms being pivoted together at the points 4: and one arm of each pair is extended beyond the yoke so formed, to provide the upper and lower projections 5 and 6 respectively. The

arms 2 of the upper section of the yoke are riveted or otherwise rigidly secured to gether, while the arms 3 of the lower sections are removably secured together by means of the bolt and nut 8 which will permit the yoke to be readily engaged with the neck of an animal and the forward edge of the projections 5 and 6 are notched as shown at 9.

Pivoted to the outer face of each arm on each section of the yoke and about midway of the ends thereof, is an additional arm l0, the adjacent arms oneach side of the yoke being brought together at their outer ends and pivoted at the points l1. Carried on the pivot points l1 between the arms 10 are the spurs l2.

From the construction described it will be appreciated that as the projections 5 and 6 are forced rearwardly to cause the sections of the yoke to be swung ony their pivo-ts,.the

spurs carried on the arms 10 on the sides of the yoke will be forced inwardly toward the plane of the projection of the longitudinal center of said yoke. In order to limit the movement of the sections of the yoke in the one ldirection to retain the device in its normal position, the lower ends of the arms of the upper section of said yoke are beveled, as shown at 13 to abut the upper edges of the arms 10 which are carried on the lower section of said yoke. The engagement of the arms l0 with the arms of the upper section of the yoke may be seen in Fig. l of the drawing.

In practice, the device is adapted to be applied to the neck of an animal in the manner shown in Fig. l of the drawing, this application of the device to use being` accomplished through the medium of the bolt and nut 7 and 8 respectively. Aafter applying the device to the neck of an animal, the same is disposed to its ineffective and normal position so that the arms 10 with the spurs 152 thereon are in their outspread position. In this position, the projections 5 and 6 are disposed above and below the neck of the animal and thus it will be seen that as the animal attempts to poke his head through a fence, these projections are adapted to contact with the wires o-r the like to cause t-he sections of the yoke to be swung on theirI pivots. By swinging the yoke in this manner, the spurs l2 will obviously be forced inwardly toward one another to bind against the neck of the animal and give him considerable pain. The animal will thus be prevented from poking his head beyond the inclosure. The joints between the parts of the device, however, are reasonably loose and the animal by working his head downwardly and thence upwardly several times, may force the' device to its initial. position.

From the foregoing it will be seen that I '.3' have provided a simple, inexpensive and efficient means for carrying out the objects of the invention and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minorI details of construction may be resorted to without departing from the spirit or sacrificing any of the principles and spurs carried at the rear ends of said pivoted arms and disposed inwardly to- 3Q ward one another as the sections of the yoke are swung in one direction.

2. A device of the class described comprising a yoke formed in sections pivoted one to the other, projections formed on the sections of said yoke extending above and below the same, a pair of rearwardly extending arms pivoted to the sides of each section of said yoke, the adjacent arms on each side of the yoke being pivotally connected together at their rear ends, and spurs carried on the pivot points at the rear ends of said last referred to arms, said spurs being disposed inwardly toward one another as the yoke sections are bent rearwardly,

and certain of the aforesaid arms being adapted to cooperate with portions of one yoke section to limit the forward pivotal mov-ement of said sections.

ln testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
